Mastitis beat me

My baby girl is almost 7 wks old and I tried to breastfeed but couldn’t get a good enough latch and when we did it was extremely painful so I decided to exclusively pump well 5 out of these 7 wks I’ve had clogged ducts no matter what I did and I ended up with mastitis in my right breast the only one that always got clogged, I physically and mentally can’t deal with the pain anymore as bad as I feel about it but I’ve decided to switch my baby to formula and let my supply dry up which shouldn’t take but a couple days since I was only producing a few ounces each pump...I’ve already been guilted and am just looking for positivity and support 😞
